Table 4.
Stratification of risk of survival in post-PV MF according to the Myelofibrosis Secondary to PV and ET Prognostic Model (MYSEC-PM) (adapted from [181]). Patients are classified into low (score 0–10), intermediate 1 (score 11–13), intermediate 2 (score 14–15) or high (score > 16) risk groups. The MYSEC-PM is available online as a risk calculator (http://www.mysec-pm.eu/, accessed on 2 November 2020).
| Risk Factor | Score |
|---|---|
| Haemoglobin < 11 g/dL | 2 |
| Circulating blasts ≥3% | 2 |
| CALR-unmutated 1 | 2 |
| Platelets < 150 × 109/L | 1 |
| Constitutional symptoms | 1 |
| Age | 0.15 per year |
